Today, physicist Eugene Bagashov concludes his remarkable three-part analysis of Oumuamua, the mysterious object which is thought to be our solar system’s first interstellar traveler. In previous episodes, Eugene has explored several enigmas, including the puzzle of the object’s mysterious acceleration as it moved away from the Sun. While this episode was in production, Eugene made a stunning discovery that may provide an essential pathway to understanding Oumuamua’s trajectory. As Eugene explains, this discovery relates directly to measurements of the interstellar magnetic field.
